I 'm working on an application using rad studio 2009 (c++) and mySQL. I want to build a setup so I can set up my application and on other PCs without installing and rad studio. As far as I 've searched, I will need some dlls. Does anyone know what dlls? I couldn't find out...
please help!
For C++ Builder if you don't use runtime packages and you link against the static RTL then you don't need to supply anything beyond the compiled .exe.
I couldn't say what you need for the database connection, but I imagine it is documented and Johan has provided you with an answer that addresses this part of your question.
Dependency Walker can be used to investigate the dependencies.
You need libmySQL.dll
and if you're using dbExpress you'll also need: dbxmys.dll
If you're using ZEOS you'll only need the libMySQL.dll, but AFAIK only ZEOS 7 alpha works in Unicode Delphi/C++ Builder
Be careful to make sure libMySQL.dll is is the exact version that goes with the MySQL server you are connecting against.

UWP App not being able to work with MySql
I have made an app in UWP and instead of using SQLLite which seems to be the norm for Visual Studio 2015 I want to use MySql. I have already connected my Azure mysql database to Visual Studio via the 'Server Explorer'.
I'm using MySQL Workbench to update my tables within my connected database from Azure but I cannot actually write any code to access my tables as whenever I try to install MySql.data/.entity/etc in the NuGet Package Manager I get an error.
nuget error
I tried downloading the Mysql installer, the Mysql drivers for Ado and ODBC. I even tried downloading the MySql for Visual Studio option as I found out that Visual Studio is not compatibile with MySql and instead requires the MySql for Visual Studio download but I still have errors whenever I try to use MySql in my code as I need an assembly reference for it but I'm having no luck in being able to get one that doesn't error.
Does anybody have any idea how I could actually use MySql within Visual Studio 2015?
This is what I've been using as my guideline but I can't seem to get past the Mysql.data errors when installing.

I have seen a lot of people talk about this but there is no one straightforward fix (I've tried a lot of the fixes, one in particular being to use Vs13 to install Mysql in the Nuget package manager and then it should update within VS15 but as my app is a UWP VS13 does not actually load/read it so that idea isn't good to me, might help anyone else though)
Starting with 6.7, Connector/Net fully supports building Windows Store apps. But using Connector/Net RT is not by install the Nuget package, it just reference the MySql.Data.RT.dll assembly according to MySQL Connector/Net Developer Guide:
Using Connector/Net RT is easy. Simply create a Windows Store application using Visual Studio and then reference the MySql.Data.RT.dll assembly in your project. The code you write should be exactly the same as for normal Connector/Net (including using same namespace MySql.Data.MySqlClient) except for the differences listed above.
You may find this dll at C:\Program Files (x86)\MySQL\Connector.NET 6.79\Assemblies\RT if you have install the connector. You can also download the mysql-connector-net-6.7.9-noinstall.zip to find this file inside the folder. I also have a MySql UWP sample before and has the dll here. Right click your project and add reference for this it will work.
More details please reference this sample
I am developing a Green Field Application in ASP.NET 5 using Visual Studio 2015.
I want to know that if I am running it in Linux environment the database used is MySql Workbench
How we do this?
It is my core problem in doing this business.
https://dev.mysql.com/doc/connector-net/en/connector-net-installation-unix.html
https://dev.mysql.com/doc/connector-net/en/connector-net-installation.html
This page clearly mention that you can use Mysql.Data.dll on any framework. If mysql.data.dll library is not working for you. You can compile it yourself on your linux machine.
MySql support Linux environment also. So You will not face any major problem.
But yes, You will have to write Table & column names in small letter in your queries otherwise it will give error.
I installed the Xamarin studio for windows which is a bundle of MonoDevelop and GTK#. I double click and nothing happens.
First thing, this is the log from the IDE.
Second thing, Bug 10558 Is the same problem but unfortunately post dates back to 2013 which about version 4.0. The fix they mentioned which is updated MonoDevelop.Core.dll file did not work.
3rd thing, GTK# bin directory is added to the environment variable, a couple of posts on the internet says that something wrong with "Win32 DLL search path", unfortunately no steps to help.
4th thing, I tried Xamarin universal installer but I press continue and nothing happens.
Update: I have Windows 7 Professional 64-bit with .NET Framework 4.0 installed.
Update 2: It used to work with me before. I don't know what has changed after I formatted my PC few months ago. I found this link on Bug 10558 which might be helpful but I did not understand it. Also found this patch which I didn't know how to apply it.
Any help is appreciated.
The exception you meet, is a typical one when running binaries compiled against .NET 4.5 on a .NET 4.0 only system.
Microsoft did move some key types between assemblies, which led to such exceptions, and there is no way to fix that except upgrading your system to .NET 4.5.
For Xamarin/Mono guys, they should modify the installer to inform end users about this change. They should also update web pages, such as this MonoDevelop page, which still says 4.0 is enough (no, 4.5 is required),

I've been searching around the web trying to find out how to use MySQL in a XAML project.
I've seen a bunch of examples where functions like MySqlConnection(...) are used and so forth, but none of them mentions if a specific assembly is necessary or if it's something you need to download first - like a dll.
Something like that is needed since it doesn't work straight away.
Anyone knows that?
You have to download and install MySql .Net Connector. Tool provided by MySql to connect with .net. This will have the assemblies used to connect .Net Applications to MySql.
I upgraded my Delphi to 2010 version and I tried to open and run application written in Delphi 2006. The app is using mysql by dbexpress with libmysql.dll and a second driver found somewhere on the Internet.
I can't run it on 2010. I'm always getting "missing libmysql.dll library". I tried to get new version of it but it didn't help. Copying this library into almost all system directories didn't help.
I'm out of any ideas what to do, how do I connect to database :(
It's most probably a unicode problem. PChar is no longer a pointer to an ansistring, but a pointer to a unicodestring. Try and upgrade the dbexpress driver. I don't mean the dll, but the dbexpress wrapper code. I'd need a little more information to help further though.
check you have dbxmys.dll available to your app too (in the exe dir or on the path)
